confusing connection problems

[Gadget.man]

new connection as of 3rd febuary i assume i'm still on the training mode

i was connected at 5mb last weekend and told this should be my speed when a sky adviser spoke to me this went down to 3mb during the week

ADSL Link Downstream Upstream
Connection Speed 3072 kbps 800 kbps
Line Attenuation 47.0 dB 27.5 dB
Noise Margin 14.7 dB 16.0 dB

all during the week the noise margin has been between 3.4 or as low as 1.4

After going out early this morning i came back to find no connection either broadband or landline i phoned sky they said the line was ok. they asked me to check the filters which i did and the corded phone. when i swapped filters it worked and now i have the above stats. Funny thing is that last saturday i had to swap filters again due to a similar problem. I've requested replacement filters just in case they are the problem which should arrive in 3-5 days.

so with my new stats as above should i be getting 5mb ?

Leave it on 24/7 and it should speed back up after a few days.
See if you have a noisy line, pick up the handset and press a number to clear the dial tone, the less noise you hear the better, any noise will mess with your speeds.

Various ISPs, including Sky, send out fairly cheap microfilters. The quality varies hugely and typical shelf life is around 2 years. A microfilter will also need to be installed on every telephone extension.

If you have an NTE5 master socket you may wish to consider fitting a filtered faceplate. They tend to last a little longer and as they filter the ADSL signal at the master socket, they also isolate any internal sockets, reducing any interference with the ADSL signal.

ive tried to upload a picture of my phone socket as i am constantly being asked by sky if i have any other bt sockets i don't think is the only one. will i be able to unscrew this and use the test socket ?

edit

the noise margin has gone from 14.7 this morning to 3.4 this evening what could be the reason ?

That socket does not have a test socket.

If you could remove the faceplate, you will see if there is a yellow capacitor, the size of a AAA battery, behind it. This would identify it as the Master Socket.

If you could post a photo of what is behind the socket, it would be useful too.

As you are unsure whether it is the only socket, it may be a good idea to trace the telephone cable coming in from the outside. As daft as it sounds, sometimes BT has installed Master Sockets in the loft before now, so please be prepared to see where it goes.

P.S. What you have there is not an NTE5 socket.

sorry i made a mistake in my reply this is the only socket i have its a small apartment/flat and am sure no other connections are here. no loft etc i will have to get a screwdriver none available here to get the faceplate off i've done this for my parents but this looks different to my that one i did it to get better speeds and it did work so i understand what you mean. thanks

If it isn't external (a noisy line or bleed over) just about anything electrical near your phone lines and router. Cordless phones are often a problem or a TV even.

nothing is on other than a tv the phone is corded. The db is again 6.5 while yesterday it was 14.7. I'll be getting a screwdriver from parents and will post the pictures of whats behind the bt socket later today or early next week. thanks for the advice everyone
